One of the unique aspects to 13th Age are Icons, they are the equivalent of the powerful NPC's that aid or oppose your player's in the course of the campaign.
Here is how the Icons are represented in my Weird War Stories setting:
The Crusaders are the Losers.
The Diabolist is the Ultra-Humanite.
The Dwarf King is G.I. Robot
The Elven Queen is Madame Xanadu.
The Emperor is the Unknown Soldier.
The Great Gold Wyrm is Sgt. Rock.
The High Druid is Solomon Grundy.
The White Queen is Mary, Queen of Blood.
The Orc Lord is the Iron Major.
The Hierophant is the Haunted Tank.
The Prince of Shadows is Blackhawk.
The Three are Abnegazar, Rath, and Ghast.
